Introduced with 4th Gen Xeon Scalable "Sapphire Rapids" processors are various new accelerators available on select SKUs or via the Intel On Demand offering.

CPU microcode updates are commonly done in the name of security fixes and resolving functionality issues.. In recent years, CPU microcode updates have been a much more common -- and important -- occurrence. While all modern CPUs rely on microcode it's just a matter of whether the version used is baked into the hardware or an updated version loaded by the BIOS or OS at boot time, a "vocal minority" of users are unhappy with CPU microcode being included in Libreboot ROMs. Thus moving forward there will be alternative builds of Libreboot for different motherboards with the CPU microcode stripped out in the name of software freedom...
